Aqua Clarus Maintenance Instructions

A quick check can pick up changes early

WCTNZ® recommends a brief external check each week. Look for alarms, unexpected water around the unit or collection lid, new odours, unusual noise and obstructed service access. Keep panels and lids closed.

Record any concerns when they occur and review the care record monthly. This is a suggested owner routine; follow any more frequent checks included in your service plan.

Keep the tasks and dates together

*Three-monthly primary-filter care is the starting interval described for the GreyFlow manual-filter pairing. Use the instructions for the collection device installed at your property.

Keep the upstream equipment accessible

The collection filter intercepts material before transfer to the treatment cabinet. Use the cleaning method for that collection device, including its isolation, hygiene and waste-handling instructions.

Only carry out this task yourself where the instructions and handover training allow it. Do not leave the system running without its filter or change its screen grade on your own initiative.

Look after each treatment barrier

The service technician checks biological circulation and treatment cycles, membrane performance, UV operation, pumps, blower, controls and alarms. The visit also addresses accumulated residuals and their approved removal route.

Membrane cleaning, UV-lamp replacement and changes to operating settings follow the instructions for the components fitted. Keep the service report, including any replacement parts and follow-up work.

Care for storage and delivery too

Keep treated-water tank lids, labels and access points intact. The service plan should include tank hygiene, the reuse pump, backup water and any irrigation filters or flushing points.

Report persistent loss of supply, repeated pump cycling, leaks or signs that stored water has deteriorated. Do not add a temporary drinking-water hose to the greywater tank or pipework.

Keep a service history that is useful

For each visit, record the date, person attending, equipment checked, readings taken, parts replaced, residuals removed, sample or laboratory references, faults found and any work still outstanding. Include the next due date and any instructions about returning to reuse.

Keep commissioning results, drawings, instructions and service reports together for the life of the system, and pass them to the next owner. Recordkeeping requirements in the site approvals and service agreement also apply.
